//! Observability infrastructure for FraiseQL server
//!
//! Provides OpenTelemetry integration for:
//! - Distributed tracing (spans, trace context)
//! - Structured logging with trace context
//! - Metrics collection (counters, histograms, gauges)
//! - Context propagation across async boundaries
